Abstract
A combination of a tractor and an implement is pulled by the tractor. A draw bar is coupled to the tractor so as to be pivotable about a vertical axis. The implement is supported on the ground by wheels and comprises a cultivating element for cultivating a field. A control device is usable to activate a first actuator with which the a position of the draw bar is changeable in relation to the implement, where the control device can be operated in order to activate the first actuator in such a manner that the latter adjusts the draw bar with the effect of moving the implement toward the outside of a curve.
Claims10
A combination of a tractor and an implement which is pulled by the tractor, the combination comprising:
- a position-determining device for determining a position of a the tractor or the implement relative to a field;
- a draw bar coupled to the tractor so as to be pivotable about a vertical axis;
- the implement supported on the ground by implement wheels and comprising a cultivating element for cultivating a field;
- a control device usable to activate a first actuator with which a position of the draw bar is changeable in relation to the implement, the first actuator coupled pivotably between the drawbar and a chassis of the implement, where the control device can activate the first actuator in such a manner that the first actuator adjusts the draw bar with the effect of moving the implement toward an outside of a curve to reduce a turning radius of the combination if the determined position is established in a headland or an end of the field in accordance with a stored plan of the field.
A method for moving a combination of a tractor and an implement which is pulled by the tractor by a draw bar coupled to the tractor so as to be pivotable about a vertical axis, is supported on the ground by wheels and comprises a cultivating element for cultivating a field, over a field, the method comprising:
- determining a position of a the tractor or the implement;
- activating, by a control device, a first actuator with which a position of the draw bar is changed in relation to the implement, the first actuator coupled pivotably between the drawbar and a chassis of the implement;
- taking into consideration a steering angle of the tractor in such a manner that the first actuator adjusts the draw bar to move the implement toward an outside of a curve to reduce a turning radius of the combination if the determined position is established in a headland or an end of the field in accordance with a stored plan of a field.
